Personal care device

Abstract

A device such as an electric shaver includes a working head attached to a handle for moving the working head along a skin surface, wherein at least one working tool is moveable relative to the handle under a skin contact pressure by a support structure to allow for pivoting of the working head's skin contact contour relative to the handle, wherein a biasing device is provided for biasing the working tool.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a personal care device, in particular hair removal device such as electric shaver, comprising a working head attached to a handle for moving the working head along a skin surface, said working head including at least one working tool defining a skin contact contour of the working head, wherein said at least one working tool is movable relative to said handle under a skin contact pressure by means of a support structure to allow for pivoting of the working head's skin contact contour relative to the handle, wherein a biasing device is provided for biasing said working tool. The invention also relates to a method of controlling such personal care device.BACKGROUND OF THE INVENTION[0002]Hair removal devices such as epilators, beard trimmers and electric shavers usually have one or more cutter elements driven by an electric drive unit in an oscillating manner where the cutter elements reciprocate under a shear foil, wherein su...

Benefits of technology

[0010]A further objective underlying the invention is to allow for easy self-adaption of the working tools of the working head to complex skin contours over a wide range together with a gentle treatment of the skin, but still providing for a good feeling of control when pressing the working head against a skin portion to achieve thorough treatment.

[0019]In addition or in the alternative to such spring device, the working head may include at least one braking device to dampen or brake the movements of the working head relative to the handle and / or of the working tool relative to a working head frame, wherein such braker may be adjusted by the adjustment actuator to provide for less braking action or more braking action to decrease and increase stiffness of the working head.

Problems solved by technology

Although such shavers are used on a daily basis by most users, it is sometimes difficult to operate and handle the shaver indeed perfectly.

Due to different preferences and habits of different users, often the shaver is not operated in its optimum range.

Said adjustable parameters are automatically controlled by fuzzy logic to balance the influence of the different input signals indicative of the different working parameters but, the achieved self-adjustment of the shaver is still insufficient in terms of fitting different user's needs and different user's preferences.
